Description

Technical Field

[0001] This invention relates to the field of fabric cleaning machine technology, and in particular to a modular fabric cleaning machine and cleaning method. Background Technology

[0002] Sofas, carpets, curtains, leather chairs, and other fabric items accumulate dust, bacteria, and stubborn stains over time. These can usually be cleaned using a fabric cleaning machine. A fabric cleaning machine typically includes a main unit, a clean water tank, a wastewater tank, and cleaning heads. The cleaning head is connected to the main unit via a hose and is equipped with a water spray nozzle and an air intake.

[0003] When the fabric cleaning machine cleans stains on the surface of fabric products, the liquid in the clean water tank is supplied to the spray nozzle of the cleaning head through a water pump and liquid supply pipe. The cleaning head sprays clean water or cleaning solution onto the surface of the fabric products, causing the liquid to dissolve the stains. At the same time, the wastewater is drawn in through the air intake of the cleaning head and connected to the wastewater tank of the fabric cleaning machine through a hose to achieve wastewater collection.

[0004] In existing fabric cleaning machines, the hose connecting the cleaning head and the main unit needs to integrate a clean water supply pipe, resulting in a large hose diameter. In addition, a water pump is required to achieve the liquid supply, which leads to a complex internal piping structure in the main unit of the fabric cleaning machine, resulting in high cost and low reliability. Summary of the Invention

[0005] The purpose of this invention is to provide a modular fabric cleaning machine and cleaning method to solve the problems of complex internal piping structure, high cost, and low reliability of fabric cleaning machines.

[0006] To achieve the above objectives, in one respect, the present invention provides a modular fabric cleaning machine, comprising:

[0007] The main unit of the cleaning machine is equipped with a sprayer positioning section and a wastewater tank positioning section.

[0008] A sprayer, which is placed in the sprayer positioning section;

[0009] A wastewater tank, which is detachably installed in the wastewater tank positioning part;

[0010] The cleaning head is connected to the main unit of the cleaning machine via a connecting tube.

[0011] As a further description of the above technical solution:

[0012] The main unit of the cleaning machine is equipped with a blower assembly for generating negative pressure suction. The handle is located above the blower assembly, and the sprayer and wastewater tank are symmetrically arranged on both sides of the handle.

[0013] On the other hand, the present invention also discloses a cleaning method for the modular fabric cleaning machine described above, comprising the following steps:

[0014] S1. Remove the sprayer from the main unit of the cleaning machine;

[0015] S2. Aim the sprayer nozzle at the stained area on the fabric and spray cleaning liquid to create wastewater;

[0016] S3. Start the cleaning machine main unit. The fan assembly generates negative pressure suction. Use the cleaning head to absorb the sewage. The sewage enters the sewage tank through the connecting pipe, sewage connector pipe and sewage inlet.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0018] 1. In this invention, the fabric cleaning machine adopts a modular design, replacing the clean water tank of the traditional fabric cleaning machine with a sprayer that can be detached and used independently. This separates the clean water spraying process from the wastewater recycling process, which not only effectively simplifies the internal piping structure of the fabric cleaning machine, but also allows the connecting pipe to retain only the function of recycling wastewater. This results in a smaller diameter and simpler structure of the connecting pipe, allowing the connecting pipe and cleaning head to be separated from the main unit of the cleaning machine, facilitating cleaning and storage. Ultimately, this achieves a reduction in cost, an increase in reliability, and convenient storage for the fabric cleaning machine.

[0019] 2. In this invention, a handle is provided in the middle of the main unit of the cleaning machine, and the handle is positioned above the blower assembly. At the same time, the sprayer and the wastewater tank are symmetrically arranged on both sides of the handle, so that the center of gravity of the fabric cleaning is located in the middle, the weight is evenly distributed, and the structure is compact.

[0020] 3. In this invention, the wastewater tank of the fabric washing machine adopts a modular design. The wastewater tank body and tank cover are inserted and fixed together. A rubber ring on the tank cover ensures sealing and a secure connection, simplifying the tank cover installation structure and reducing costs. After pulling the tank cover upwards, the separation filter element can be pulled out, allowing the filter element to be separated from the wastewater tank body for cleaning and maintenance. The wastewater tank not only has a simple structure, but its installation is also simple and easy to operate, further reducing costs. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0041] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0042] Example 1

[0043] Please see Figure 1-12 On the one hand, the present invention provides a modular fabric cleaning machine, comprising:

[0044] The main unit 1 of the cleaning machine is provided with a sprayer positioning part 11 and a sewage tank positioning part 12. The sprayer positioning part 11 can adopt a sprayer positioning structure in the form of a trough, through hole, boss, etc., as shown in the figure. It is preferred to adopt a sprayer positioning part in the form of a trough. Similarly, the sewage tank positioning part 12 can adopt a sewage tank positioning structure in the form of a trough, boss, etc. A sewage inlet 121 and a gas outlet 122 are provided on the bottom surface of the sewage tank positioning part 12. The sewage inlet 121 is connected to the sewage connector pipe 13, and the gas outlet 122 is connected to the fan cavity through the exhaust duct 14. A fan assembly 15 for generating negative pressure suction is provided in the fan cavity.

[0045] Sprayer 2, which is placed in sprayer positioning part 11;

[0046] Wastewater tank 3, which is detachably installed on wastewater tank positioning part 12;

[0047] The connecting pipe 4 has one end threadedly connected to the connector of the cleaning head 5, and the other end is detachably installed on the sewage connector pipe 13.

[0048] The main unit 1 of the cleaning machine is equipped with a fan assembly for generating negative pressure suction. The handle 16 is located above the fan assembly. The sprayer 2 and the wastewater tank 3 are symmetrically arranged on both sides of the handle, so that the center of gravity of the fabric cleaning is located in the middle, the weight is evenly distributed, the structure is compact, and it is easy to use.

[0049] The sprayer can be a manual sprayer or an electric sprayer. The sprayer positioning unit 11 positions the sprayer solely based on its external dimensions, and the sprayer can be flexibly selected as a manual or electric sprayer depending on factors such as spraying requirements and cost control.

[0050] The wastewater tank 3 includes a wastewater tank body 31, a separation filter element 32, and a tank cover 33. The wastewater tank body 31 is inserted into the wastewater tank positioning part 12. A wastewater inlet cylinder 311 and an exhaust cylinder 312 are provided on the bottom surface of the wastewater tank body 31. The bottom opening of the wastewater inlet cylinder 311 corresponds to the wastewater inlet 121, and the bottom opening of the exhaust cylinder 312 corresponds to the gas outlet 122. A first partition 313 is provided between the wastewater inlet cylinder 311 and the exhaust cylinder 312. The separation filter element 32 includes a first connector pipe 321, a second connector pipe 322, and a second partition 323. The first connector pipe 321 is fitted onto the top of the wastewater inlet cylinder 311. A drain outlet is provided at the top of the first connector pipe 321. The second connector pipe 322 is fitted onto the top of the exhaust pipe 312. An exhaust outlet is provided at the top of the second connector pipe 322. A grid is provided inside the exhaust outlet. The first connector pipe 321 and the second connector pipe 322 are connected by a second partition 323. The bottom surface of the second partition 323 contacts the top surface of the first partition 313. The drain outlet and the exhaust outlet are located on both sides of the second partition 323 to effectively prevent sewage splashing. The water tank cover 33 is provided with a plug-in part for plugging into the sewage tank 31. A rubber ring is fitted on the plug-in part. The plug-in part extends into the sewage tank 31, and the rubber ring contacts the inner wall of the sewage tank 31.

[0051] The wastewater tank 31 is equipped with a quick-drain outlet, and a drain cover 34 is rotatably mounted on the wastewater tank 31, closing the quick-drain outlet. Wastewater is quickly discharged from the quick-drain outlet at the bottom of the wastewater tank 31 after the drain cover 34 is opened. A plug made of a flexible material such as silicone is inserted into the quick-drain outlet on the drain cover 34 to achieve closure.

[0052] A longitudinal partition 331 is provided on the bottom surface of the water tank cover 33, and a notch 3231 is provided on the second partition 323 for engaging with the longitudinal partition 331. The longitudinal partition 331 further prevents sewage from entering the motor after being flushed onto the top cover, and at the same time improves the deformation resistance of the sewage tank body 31.

[0053] Wastewater enters the wastewater tank 31 through the wastewater connector pipe, wastewater inlet 121, wastewater inlet cylinder 311, and the sewage outlet of the first connector pipe 321. After the wastewater and solid waste are separated from the airflow by the separation filter element 32, the airflow enters the exhaust cylinder 312 through the grid of the second connector pipe 322, and is discharged from the exhaust hole on the main body 1 of the cleaning machine in sequence through the gas outlet, the exhaust duct 14, and the fan cavity.

[0054] The wastewater tank of the fabric washing machine adopts a modular design, consisting of three parts: a wastewater tank body 31, a separation filter element 32, and a water tank cover 33. The wastewater tank body 31 and the water tank cover 33 are inserted and fixed together. The sealing and connection are ensured by the rubber ring on the water tank cover 33, simplifying the installation structure of the water tank cover 33 and reducing costs. After pulling the water tank cover 33 upwards, the separation filter element 32 can be pulled upwards, allowing the separation filter element 32 to be separated from the wastewater tank body 31, making the wastewater tank easy to clean and maintain.

[0055] The handle 16 is provided with a hanging plate 161, and the back of the cleaning head 5 is provided with a hanging block 51. The side wall of the hanging block 51 is provided with a hanging groove 511 that matches the shape of the hanging plate 161.

[0056] The cleaning head 5 can be hung on the hanging plate 161 of the handle 16 via the hanging block 51 on the back, making it easy to store the cleaning head 5. The handle 16 is specifically provided with two symmetrically arranged hanging plates 161 facing each other. The cross-section of the hanging plate 161 is "L" shaped, which effectively positions the cleaning head 5.

[0057] On the other hand, the present invention also discloses a cleaning method for the modular fabric cleaning machine described above, comprising the following steps:

[0058] S1. Remove the sprayer 2 from the main unit 1 of the cleaning machine;

[0059] S2. Aim the nozzle of sprayer 2 at the stained area on the fabric surface and spray cleaning liquid to create wastewater;

[0060] S3. Start the cleaning machine main unit 1. The fan assembly 15 generates negative pressure suction. Use the cleaning head 5 to adsorb sewage. The sewage enters the sewage tank 3 through the connecting pipe 4, sewage connector pipe 13, and sewage inlet 121 to realize sewage recycling.

[0061] Working principle: The fabric cleaning machine adopts a modular design, replacing the clean water tank of the traditional fabric cleaning machine with a sprayer 2 that can be detached and used independently. This separates the clean water spraying process from the wastewater recycling process, which not only effectively simplifies the internal piping structure of the fabric cleaning machine, but also allows the connecting pipe 4 to retain only the function of recycling wastewater. This results in a smaller diameter and simpler structure for the connecting pipe 4, allowing the connecting pipe 4 and the cleaning head 5 to be separated from the main unit 1 of the cleaning machine, making cleaning and storage easier. Ultimately, this reduces the cost of the fabric cleaning machine, improves its reliability, and makes it more convenient to store.

[0062] Example 2

[0063] Based on the above embodiments, this embodiment further improves upon the following technical solutions: A first slot 123 is provided on the side wall of the tank-type sewage tank positioning part 12, and a first locking block 124 is provided on the side wall of the first slot 123. The first locking block 124 is elastically connected to the housing of the main unit 1 of the cleaning machine. After the first locking block 124 extends out of the side wall of the first slot 123, it forms a locking tongue. The cross-section of the locking tongue is "V" shaped. A first connecting block 314 for insertion into the first slot 123 is provided on the back of the sewage tank 31. A slot 3141 corresponding to the locking tongue is provided on the first connecting block 314.

[0064] To prevent the sewage tank from detaching from the sewage tank positioning part 12, the sewage tank body 31 is locked by the insertion of the first connecting block 314 on the back into the first slot 123 on the side wall of the sewage tank positioning part 12. The locking tongue is inserted into the slot 3141 of the first connecting block 314. Since the locking tongue has a "V"-shaped cross-section and bevels on its upper and lower sides, during the installation and removal of the sewage tank, only increased installation or removal force is needed to push the locking tongue back using the first connecting block 314, thus enabling the installation or removal of the sewage tank. The sewage tank not only has a simple structure, but its installation is also simple and easy to operate, further reducing costs.

[0065] Example 3

[0066] Based on the above embodiments, this embodiment further improves upon the following technical solutions: a suction port 52 is provided on the cleaning head 5, a brush block mounting chamber 53 is provided below the suction port 52, a snap-fit ​​plate 531 is provided at the bottom of the brush block mounting chamber 53, a brush block 54 is inserted into the brush block mounting chamber 53, a toggle plate 541 is provided at the bottom of the brush block 54, and a waist-shaped hole is provided on the toggle plate 541 for engaging with the snap-fit ​​plate 531.

[0067] Wastewater from fabric products is sucked into the cleaning head 5 through the suction port 52 and further fed into the main unit 1 of the cleaning machine through the connecting pipe 4. During the cleaning process, the brushes on the brush block 54 below the suction port 52 can also be used for brushing. The brush block 54 can be detached and installed by using the engagement of the actuating plate 541 and the snap-on plate 531, realizing a modular design that is easy to maintain and replace. The protruding actuating plate 541 also makes it easy to pull out the brush block 54 and control the brush block 54 to be installed in the brush block installation chamber 53.

[0068] In addition, the surface of the cleaning head 5 on the upper side of the suction port 52 is provided with several parallel raised ribs 55, which effectively prevents the cleaning head 5 from deforming and avoids clogging of the suction port 52. The raised ribs 55 have a curved surface to prevent scratching fabric products.

[0069] Example 4

[0070] Based on the above embodiments, this embodiment further incorporates the following improved technical solutions:

[0071] The connecting pipe 4 is provided with a first connector 41 at its end. The first connector 41 is inserted into the sewage connector pipe 13. A spring piece 411 is provided on the side wall of the first connector 41. A protrusion 412 is provided on the surface of the spring piece 411. A through hole 131 for engaging with the protrusion 412 is provided on the side wall of the sewage connector pipe 13. One end of the spring piece 411 extends out of the sewage connector pipe 13 and forms a bent part 413. The bent part 413 contacts the end face of the sewage connector pipe 13.

[0072] The connecting pipe 4 is inserted and locked to the sewage connector pipe 13 through the first connector 41, and quick release is achieved through the spring piece 411. The spring piece 411 has elastic deformation capability. By pressing the bending part 413, the spring piece 411 can be moved away from the inner wall of the sewage connector pipe 13, thereby causing the protrusion 412 to disengage from the through hole 131, and then the connecting pipe 4 can be pulled outward.

[0073] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
